Everyone loves pizza, and there’s no better pizza than homemade.

One of the best ways to improve your craft of photography is by shooting film.

After over 7 years of off-and-on development (but mostly off), I am finally releasing the first version of Tisp, the tiny lisp programming language.

Any beginners C tutorial will teach the basics of the C standard library’s file reading functions (eg fopen).

At the start of the 20th century two new revolutionary and counterintuitive areas of physics were being developed, quantum mechanics and special relativity.

I’ve used a mechanical keyboard for many years now.

C macros, while being extremely powerful when used correctly, can also be the cause for a lot of unnecessary headaches if you are not aware of their limitations.

This article is based on research I did as a freshman undergrad, see the full project here.

trig identities $$\sin^2 \theta + \cos^2 \theta = 1$$ $$1+ \tan^2 \theta = \sec^2 \theta$$ $$1+ \cot^2 \theta = \csc^2 \theta$$ $$\sin(a \pm b) = \sin(a)\cos(b) \pm \cos(a)\sin(b)$$ $$\cos(a \pm b) = \cos(a)\cos(b) \pm \sin(a)\sin(b)$$ $$\sin(-\theta) = -…

derivation of the quotient rule The quotient rule is used to take the derivative of a function with divided expressions: $$ \left(\frac{u}{v}\right)’ = \frac{vu’ - uv’}{v^2} $$ It is possible to prove this rule by utilizing the definition of the derivativ…

libsl is an extremely small library used to write better and clearer C programs.

$ \newcommand{\e}[1]{ \times 10^{#1}} $ constants $m_e = 9.11\e{-31} kg = .511 \frac{MeV}{c^2} = 5.4858\e{-4} u$ $m_p = 1.673\e{-27} kg = 938 \frac{MeV}{c^2} = 1.007276 u$ $m_n = 1.675\e{-27} kg = 940 \frac{MeV}{c^2} = 1.008665 u$ $u = 1.6605\e{-27} kg =…

Like most things in Vim, the indenting (tabs) system is complex making it extremely flexible so that it can fit any programming language or use case.
